A master brake cylinder arrangement for a hydraulic motor vehicle brake system, comprising a master brake cylinder housing with a cylindrical recess and at least one substantially annular groove which is oriented transversally to a longitudinal axis of the cylindrical recess and which is axially delimited by a protruding housing portion. The master brake cylinder arrangement also comprises at least one pressure piston which can be displaced axially in the cylindrical recess of the master brake cylinder housing and which is guided in a sealed manner by means of at least one seal element arranged in the groove. The housing portion has an edge portion which faces the seal element and an edge portion which faces away from the seal element when viewed in the axis-containing longitudinal section. The edge portion facing the seal element and the edge portion facing away from the seal element have a curved contour when viewed in the axis-containing longitudinal section, the edge portion facing the seal element and the edge portion facing away from the seal element being curved to different degrees.
